PIC24EP128GP202-H/SP Overview
A PIC microcontroller is a programmable embedded processor that integrates CPU, Flash, RAM, and peripherals on a single die, forming the lowest level of the embedded computing hierarchy: microcontroller -> embedded MCU -> digital signal controller -> semiconductor. The PIC24EP family uses a modified Harvard architecture with a 16-bit data path, 24-bit instruction width, and hardware DSP support for signal-processing tasks. It is a Digital Signal Controller (DSC) class device, bridging generic microcontrollers and dedicated DSPs.
Key features of the PIC24EP128GP202 include up to 70 MIPS performance from a single 3.0V to 3.6V supply, internal operational amplifiers, a Charge Time Measurement Unit (CTMU) for capacitive touch and current measurement, a Peripheral Trigger Generator (PTG) for automating peripheral sequencing, and superior ADC performance aimed at high-end general-purpose applications. The on-chip op amps reduce external analog BOM in sensor-conditioning circuits.
The architecture integrates a high-speed 70 MIPS core with multi-channel 10-bit/12-bit ADCs, PWM, I2C, SPI, UART, and enhanced timers. The combination of op amps + CTMU + PTG means a single chip can handle analog front-end conditioning, capacitive sensing, and timing-critical event sequencing without external glue logic.
Typical applications include automotive body and powertrain subsystems, industrial motor control, white-goods inverters, UPS power-factor correction, multi-loop PID control loops, sensor conditioning with on-chip op amps, and capacitive-touch user interfaces. The wide temperature range also suits outdoor industrial and renewable-energy installations.
When designing with this part, plan input clock options (HS, XT, EC, FRC) early because the 70 MIPS throughput depends on stable clocking; place decoupling caps within 5 mm of each VDD/VSS pair. For automotive designs, ensure the -H grade's 150C junction limit is respected at maximum ambient plus self-heating derating.

Automotive Body Electronics
The PIC24EP128GP202-H/SP fits automotive body controllers (BCM), HVAC panels, and lighting modules because of its AEC-Q100 qualification, -40C to +150C operating range, and 128 KB Flash that comfortably hosts CAN/LIN stacks plus application logic. Its 70 MIPS core runs PID loops for seat-position memory and mirror-folding at sub-millisecond rates, while the on-chip op amps condition sensor inputs without external analog front-end cost. Compared to lower-temperature -I grade parts, the -H grade is the only family member permitted for under-hood or sun-exposed cabin positions per Microchip's automotive qualification matrix.
Recommended
Industrial Motor Control
The PIC24EP128GP202-H/SP drives BLDC and PMSM motor controllers in industrial settings where the -H grade's 150C junction limit tolerates high-ambient cabinet temperatures near inverters. Its 70 MIPS core executes Field-Oriented Control (FOC) at 20 kHz PWM rates for pumps, fans, and small servos, while the integrated op amps close current-sense feedback loops without external analog ICs. The Peripheral Trigger Generator (PTG) automates ADC sampling and PWM updates deterministically, removing jitter that would otherwise degrade torque ripple. Compared to lower-cost -I grade parts, the -H grade's AEC-Q100 pedigree guarantees long-term reliability in harsh industrial environments.

Key Differentiators
- Highest temperature grade in PIC24EP family (-40C to +150C) (vs PIC24EP128GP202-I/SP)
- Through-hole SPDIP package for prototyping and rugged mounting (vs PIC24EP128GP202-I/MM)
- AEC-Q100 qualified with -H temperature grade (vs PIC24EP128GP202-E/SP)
Design Notes
Power the PIC24EP128GP202-H/SP from a 3.0V to 3.6V regulated rail such as the Microchip MCP1700 LDO. Place a 100 nF decoupling capacitor within 5 mm of each VDD/VSS pair, plus a bulk 10 uF tantalum or ceramic capacitor on the main VDD rail to handle inrush during flash programming. The device's 70 MIPS performance draws approximately 30 mA active; ensure the LDO can supply at least 50 mA to leave margin for transient spikes.
The -H temperature grade supports up to +150C junction, but at sustained 70 MIPS workloads the self-heating rise can reach 10-15C above ambient in the SPDIP package. Estimate junction temperature as TJ = TA + (theta_JA x PD), where theta_JA for the 28-SPDIP is approximately 60 C/W and PD is the active current draw times VDD. In enclosed automotive or industrial cabinets, derate ambient by 15C or add forced-air cooling to keep TJ below 130C for long-term reliability.
Route the crystal oscillator traces (OSC1/OSC2) as short, symmetrical differential pairs with a ground guard on both sides, keeping trace length under 10 mm to avoid EMI pickup. Place the MCLR pull-up resistor and decoupling capacitor within 5 mm of the MCLR pin to ensure reliable reset during voltage dips. The 28-SPDIP is through-hole, so use a socket for development; for production solder directly with a clean, lead-free profile per IPC J-STD-020.
Do not exceed 3.6V on VDD even briefly, as the PIC24EP family is not 5V tolerant on I/O. Ensure the ADC reference voltage (AVDD) is tied to the same 3.3V supply or a filtered reference, not the noisy switching rail. When using the internal op amps, route their inputs as differential pairs and avoid sharing analog and digital ground returns through the same via to prevent ground-loop noise pickup.
Compliance Information
RoHS, REACH, and halogen-free compliance per Microchip product page. AEC-Q100 Grade 0 qualified for the -H temperature grade. Lead-free reflow profile per IPC J-STD-020.
